Drag that link into your bookmarks bar. Click it on any Flickr user's photos homepage or set view page to
be redirected to the corresponding page on Darkroom.

Why?

The photo size on Flickr photo pages is too small and you can't navigate between photos
in any larger view besides the (Flash, yuck!) slideshow. Darkroom presents photos nice and big with the
best kind of navigation, scrolling.

So after many years Flickr improved their photo pages making Darkroom redundant. My happiness as a Flickr user outweighs my disappointment as Darkroom developer. C’est la vie.
